The simulated register allocator has issues (at least when compiling for ARM). It may cause compile time crashes. Under some circumstances the virtual register map can end up corrupted and (in some cases) cause a crash. I don't know if this issue also affects x86. Register allocation simulation can be disabled by setting SIMULATE_REGISTER_ALLOCATION to NO in the sched.ini file
